Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The joint between the femur and the tibia; called the knee joint in humans.






2. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






3. Another name for a pivot joint; one bone pivots on another in a rotary motion. The only true pivot joint is the atlantoaxial joint.






4. The joint movement that decreases the angle between two bones.






5. Small bones shaped like cubes or marshmallows; an example are the carpal bones.






6. A joint movement that consists of a twisting motion of a part on its own axis.






7. Bones that are relatively thin and flat; they consist of two thin plates of compact bone separated by a thin layer of cancellous bone. Includes skull bones and the scapula.






8. The most caudal rib or two in the rib cage; a rib whose costal cartilage does not unite with anything but rather ends in the muscle of the thoracic wall.






9. The healing tissue between the ends of a fractured bone that is eventually replaced by true bone as the fracture heals.






10. Spongy bone; a form of bone composed of a seemingly random arrangement of spicules of bone separated by spaces filled with bone marrow. Appears spongelike to the naked eye. Found in the ends of long bones and the interiors of short bones - flat bones






11. A rib whose costal cartilage joins the costal cartilage of the rib ahead of it instead of directly joining the sternum.






12. The bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone; in the living animal - it contains the external ear canal.






13. The paranasal sinus in the ethmoid bone of horses and humans.






14. The type of bone formation whereby bone grows into and replaces a cartilage model; this is the method by which most bones form in a developing fetus - starting with cartilage 'prototypes' that are gradually replaced by bone. It is also the means by w






15. A joint in which the bones are united by cartilage; also called an amphiarthrosis. Only a slight rocking motion is permitted between the bones.






16. The sievelike area of the ethmoid bone through which the many branches of the olfactory nerve pass from the upper portion of the nasal cavity to the olfactory bulbs of the brain.






17. A large channel through which large blood vessels pass carrying blood to and from the bone marrow.






18. The breastbone; a series of rodlike bones called sternebrae that form the floor of the thorax.






19. The membrane that encloses the ends of the bones in a synovial joint; consists of an outer fibrous membrane and an inner synovial membrane that produces viscous synovial fluid that lubricates the joint surfaces.






20. Ankle joint or tarsus; joins the tibiotarsus and the tarsometatarsus.






21. The vertebrae of the pelvic region; fuse to form a solid structure which forms a joint with the ilium called the sacroiliac joint.






22. Another term for the diaphysis of a long bone.






23. The cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally. Also called the pubic symphysis.






24. A hole in the bone.






25. The fibrous membrane that lines the hollow interiors of bones.






26. A band of fibrous connective tissue that is present in and around many synovial joints; connect the bones of the joint to each other.






27. A depressed or sunken area on the surface of a bone; usually occupied by muscles or tendons.






28. The group of vertebrae located dorsal to the abdominal region.






29. A beak - shaped process at the proximal end of the trochlear notch of the ulna; when it fails to unite with the ulna - an ununited process can cause the elbow joint to become unstable - leading to lameness.






30. The concave articular surface of the scapula; the socket portion of the ball - and - socket shoulder joint.






31. The paranasal sinus in the maxillary bones.






32. The 'forearm' region of the thoracic limb.






33. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






34. The first - most cranial sternebra.






35. A slightly movable cartilaginous joint - such as the pubic symphysis.






36. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






37. The main growth area of a bone developing by endochondral method; areas of bone development that are located in the main portions of the cartilage rod bone templates in the developing fetus.






38. Large - multinuclear cells of bone that absorb bone and structures and reshape or remodel damaged bones.






39. The soft material that fills the spaces inside the bones; two types of bone marrow are red bone marrow - which forms blood cells - and yellow bone marrow - which consists primarily of adipose tissue.






40. The cells that produce bone.






41. A toe that does not reach the ground - such as the first digit of dogs and cats and the rudimentary medial and lateral toes of cattle.






42. A skull bone; an internal bone of the cranium. This single bone is located just rostral to the sphenoid bone and contains the cribriform plate.






43. Tiny channels through the matrix of bone. Threadlike projections from osteocytes communicate with each other and with blood vessels through these structures.






44. A joint that allows only a rotary motion; the only true joint of this type is the atlantoaxial joint ('no joint').






45. A skull bone that is one of the internal bones of the face; forms part of the nasal septum.






46. The joint movement whereby an extremity is moved away from the median plane.






47. Skull bones that are external bones of the cranium; form the lateral walls of the cranium - contain the middle and inner ear structures - and are the skull bones that form the temporomandibular joints with the mandible.






48. The most caudal of the three pairs of bones that make up the pelvis.






49. Skull bones; external bones of the cranium. These bones make up the 'forehead' region of the skull and contain the large frontal sinuses. The cornual process in horned animals is an extenion of this bone.






50. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.
